Question

Which shows one way to determine the factors of y? - 9/2 + 54 - 45 by grouping?

a. x²(x - 9) - 5(x - 9)
b. X(X + 9) - 5(X + 9)
c. (x(x + 5) – 9(x² + 5)
d. x(x² – 5) – 9(x² – 5)

Answer 1

To determine the factors of y in the expression -9/2 + 54 - 45 by grouping, we can rearrange the terms and factor out the common factor for each group.

Step-by-step explanation:

To determine the factors of y in the expression -9/2 + 54 - 45, we can group the terms together. Rearranging the terms, we have -9/2 - 45 + 54. Now, we can find the factors of y by factoring out the common factor from each group. In this case, the common factor is -9/2. Factoring out -9/2, we get (-9/2)(1 + 5 - 6). Simplifying further, we have (-9/2)(0), which equals 0. Therefore, the correct answer is option a. x²(x - 9) - 5(x - 9).
